Donohue syndrome, also known as leprechaunism, is an extremely rare genetic disorder that affects multiple organs and tissues in the body. It is one of the many conditions cataloged in the Online Mendelian Inheritance in Man (OMIM) database, a valuable scientific resource for genetic research.

The name “Donohue syndrome” comes from its identification by Dr. William L. Donohue, who first described the condition in medical literature. The syndrome primarily affects the body’s ability to process glucose, leading to severe insulin resistance and other metabolic abnormalities.

Patient advocacy groups, such as the Donohue Syndrome Research Center, provide support and resources for individuals and families affected by this condition. They strive to raise awareness, learn more about the syndrome, and support each other through shared experiences.

Donohue syndrome is associated with mutations in the INSR gene, which plays a crucial role in insulin signaling. These genetic mutations disrupt the normal function of the insulin receptor, leading to the characteristic signs and symptoms of this condition.

The frequency of Donohue syndrome is extremely low, with only a few dozen cases reported worldwide. It is considered an autosomal recessive disorder, meaning that both parents need to carry a copy of the mutated gene for their child to inherit the condition.

ClinicalTrials.gov is a valuable resource for finding information on ongoing research studies and clinical trials related to Donohue syndrome. Additionally, additional articles and references can be found on PubMed, providing further information on the causes, signs, symptoms, and genetic studies of this condition.

Preventable medical errors kill about 22,000 patients a year, according to research from the Yale School of Medicine. That’s much less than a previously reported number of 250,000 deaths a year where medical error is to blame.

Frequency

The frequency of Donohue syndrome is extremely rare, with less than 100 reported cases in the scientific literature. It is estimated to occur in approximately 1 in 2 million live births.

This condition is caused by mutations in the INSR gene, which provides instructions for making the insulin receptor protein. These mutations interfere with the normal functioning of the insulin receptor, leading to the signs and symptoms of Donohue syndrome.

Research and studies on Donohue syndrome are limited due to its rarity. However, the advancement in genetic testing techniques has enabled the identification of the underlying gene mutations in affected individuals.

The associated signs and symptoms of Donohue syndrome are usually evident at birth or shortly after. The condition is characterized by extreme insulin resistance, resulting in severe growth failure and abnormalities in various organs and systems in the body.

As Donohue syndrome is a genetic condition, it is inherited in an autosomal recessive manner. This means that both parents of an affected individual carry one copy of the mutated gene but do not usually show signs or symptoms of the syndrome.

For more information about Donohue syndrome and associated genes, the National Institutes of Health’s Genetic and Rare Diseases Information Center (GARD) provides comprehensive resources, including references to scientific articles, OMIM entries, and patient advocacy organizations.

Additionally, PubMed and clinicaltrials.gov may have more articles and ongoing research studies on Donohue syndrome and related syndromes that can provide additional information and support.

Causes

The exact cause of Donohue syndrome, also known as leprechaunism, is not yet fully understood. However, it is believed to be a genetic condition with an autosomal recessive inheritance pattern. This means that both parents must carry a copy of the mutated gene for their child to develop the syndrome.

The syndrome is associated with mutations in the INSR gene, which provides instructions for making the insulin receptor protein. These mutations affect the functioning of the insulin receptor, leading to impaired insulin signaling in various tissues and organs throughout the body.

Research published on PubMed and other scientific resources has identified several different mutations in the INSR gene that are associated with Donohue syndrome. Each patient may have a unique mutation, and the specific mutation can influence the severity of the condition.

Donohue syndrome is extremely rare, with an estimated frequency of less than 1 in 1,000,000 live births. The syndrome is also closely related to another genetic disorder called Rabson-Mendenhall syndrome. Both conditions share similar signs and symptoms, and both are caused by mutations in the INSR gene.

Genetic testing is available to confirm a diagnosis of Donohue syndrome. Testing can identify mutations in the INSR gene and provide additional information about the specific gene mutation and its impact on insulin signaling.

While there is currently no cure for Donohue syndrome, supportive care and management can help improve the quality of life for affected individuals. ClinicalTrials.gov is a valuable resource for finding ongoing clinical trials and research studies related to the syndrome.

For more information and support, organizations such as the Donohue Syndrome Leprechaunism Network can provide resources and advocacy for individuals and families affected by the condition.

Inheritance

Donohue syndrome, also known as leprechaunism, is an extremely rare genetic condition. It is caused by mutations in the insulin receptor gene (INSR) which prevents the proper functioning of the insulin receptor. This results in severe insulin resistance and an inability to regulate blood glucose levels.

Inheritance of Donohue syndrome follows an autosomal recessive pattern, which means that an affected individual must inherit two copies of the mutated gene, one from each parent. If both parents are carriers of the mutation, each child born to them has a 25% chance of being affected, a 50% chance of being a carrier like their parents, and a 25% chance of not inheriting the mutation at all.

This syndrome has an estimated frequency of about 1 in every 2-3 million births. Due to its rarity, there is limited information and resources available about Donohue syndrome. However, there are several organizations and online resources dedicated to providing support, advocacy, and information for patients and their families.

Some of the additional rare signs and symptoms associated with Donohue syndrome include growth retardation, characteristic facial features, enlarged genitalia, and abnormalities of various organs and tissues in the body. ClinicalTrials.gov and OMIM (Online Mendelian Inheritance in Man) are valuable resources for finding information about ongoing research studies, genetic testing, and clinical trials related to Donohue syndrome.
